Seacliff Function's Andrew Harrison, The Lagoon head chef Emanuel Efstathiadis and Illawarra Hawks sponsor Tory Lavalle have all been fined over an illegal lobster haul.

A group of Illawarra businessmen involved in the illegal overfishing of Eastern rock lobster off the Illawarra coast have been penalised more than $2 million.

In a judgment handed down at Sutherland Local Court on Wednesday, magistrate David Williams imposed fines of $836,000, awarded legal costs of $492,000 and stripped the fishing company at the centre of the scam of almost $800,000 worth of shares in the state lobster management scheme.
